PPT Productivity's PowerPoint Change Shapes Painter makes it easy to copy paste shape types in PowerPoint presentations, to match a selected shape.

Simply select the shape you want to copy on your PowerPoint slide, then click the Change Shape Painter button. Next, click the shape you want to change. The Change Shape Painter will change the shape to match the copied shape style (note that it does not change the shape size, but you can use the Advanced Format Painter for this).

Double click the Change Shape Painter to activate the multi painter feature. This lets you click on multiple shapes, changing them to match the first selected shape. Multi painter mode will continue for the Change Shape Painter until you press the escape key.
